Microsoft Outlook & Active sync / Toshiba e400

I'm having problems trying to get Outlook to download my emails, I can send them okay but can't recieve them for some reason. I'm using XP Pro and outlook 2002, I have tried outlook express and its just the same. I just bought an Toshibe e400 pda abd it works fine with outlook, I recently formated my c drive and loaded oulook 2002 from the Pocket PC e400 companion CD I also use Microsoft Active Sync 3.7. Can anyone out there help me I would be over the moon if you could.
